These symptoms are similar to my HDX-5106 with a marginal
extension cord and/or overloaded breaker. I agree with Steve.
The explanation for the motor not restarting on the way up
is that the first time the motor was cold, which reduced
the resistance enough to get by on reduced voltage.
After the motor has warmed up, you need more voltage.
My tower needs its own personal 20A breaker and two 10 gauge
wires in parallel (per phase) to go 200 feet to the tower.
I previously tried lighter wiring, and it "sort of" worked,
like you are observing.
